I bought this book thinking it would help me with my university course as I prefer using Mathcad to the other more popular spreadsheet software. The book's title gives the impression it is a guide to creating mathematical groundwater infiltration models in Mathcad. I was very disappointed to discover it was in fact someone's university dissertation. It is not a textbook at all and there are no worked Mathcad examples. Consequently, it is of very limited teaching value and is also very poor value for money.
